Lewis Hamilton and Nico Rosberg hav endured a rocky relationship at Mercedes
Lewis Hamilton and Nico Rosberg were often battling for supremacy at the front of the grid

Rosberg and Hamilton were childhood friends having raced together in go-karting.

"I will of course continue to follow developments and I'm looking forward to seeing the new car and will definitely be at the track for five or six races," Rosberg added.
"We are simply the best team and have the best chance.
"But Red Bull and Ferrari can never be underestimated.
"I'm still a huge fan of our sport and I'm already excited about the first tests."
